For sure. But I think the point the @gewa trying to make is that yes in the strict academic/technical sense it is correct, however in every day English people probably use "strain" to mean Clad. But not everyone is a evolutionary biologist of some sort.

For sure. But the point of the article is that to non-expert readers, the "every day English" usage people are thinking of is misinforming them!

You are literally nitpicking the wrong people here. They're trying (well, I thought, though clearly not well enough to satisfy HN pedants) to explain the distinction in a way that conveys the fact that there are no known distinct outbreaks with different medical properties. How that's for precision?
